Danish physicist H. Ørsted made an attempt to explain the mechanism of the impact of electric current on a magnetic needle by introducing the notion of electric vortexes which escape the conductors and affect the magnet. How are these impacts actually implemented? Choose the correct statement. 
A. Around the conductor with the electric current there's an electric field which tilts the needle. 
B. Around the conductor with the electric current there's a magnetic field which tilts the needle. 
C. Around the conductor with the electric current the gravitational field tilts the needle. 
D. Around the conductor with the electric current there's a magnetic charge which tilts the needle.
